Daily Objectives #6 (September 13, 2007)                                        Dr. Sanders

By the end of today's class, you should be able to do the following:

v Making a Scientific Presentation:
  • Organize and verbally convey information on a scientific lab experiment to an audience, supplementing your talk with simple illustrations.
v Water Flow: 
  • Describe in words what makes water flow. 
v Properties of Porous Materials:
  • Define the following term: porosity.
  • Characterize rocks and sediments in terms of their porosity, giving typical ranges of values of these properties for each type of rock and sediment.

Today's Agenda:

v Presentations on water flow: Present the work you did in lab over the past week.   In your brief (2-3 minutes) presentation, please convey to the audience information on your experimental setup, your results (they may be numbers, graphs, or verbal observations), and at least one conclusion based on your experimental results.  Groups/activities:  Holey Water Bottle, Draining Work, Bucket to Bucket Transfer, Infiltration Observation, Capillary Action.

v Properties of Porous Materials: Define porosity.  Write a formula to express its meaning. Arrange a suite of samples of rock and sediment in order of increasing porosity.
